To all whom it may concern:

Be it known that I, REUBEN HALLENsrErN, merchant, of Melbourne, in theColony of Victoria, have invented certain new and useful ImprovedAppliances for Operating Sliding Doors Closing Lift or Stairway Openingsin Floors of Buildings, (patented in Great Britain October 1, 1890, No.15,541; in Belgium October 1, 1890, No. 92,171; in Austria-I-IungaryFebruary 12, 1891, No. l14,193 and No. 77,829; in Turkey October 1,1890, No. 196; in .France October 1, 1890, No. 208,578; in ItalyNovember 13, 1890, Vol. LVI, 82; in Spain November 15, 1890, No. 11,291;in Bra- Zil December 16, 1890, No.' 1,018, and in Cape of Good HopeFebruary 11, 1891, folio 666,) of which the following is aspecification.

This invention is specially adapted for 'opening and closingsimultaneously lift or stairway openings in lofty buildings 'by means ofsliding doors. This is effected by means of a vertical shaft placedparallel to but outside the lift or stairway and running from the top tothe bottom of the building. The shaft is provided on each floor with ahand-wheel, by means of which the shaft may be rotated from any floor. Abevel-pinion is keyed on the shaft belowT each floor. Each bevelpiniongears with a bevel-wheel on a transverse shaft below each floor, and bymeans of this transverse shaft motion is communicated to theconnections, whereby the sliding doors are opened or closed.

In the accompanying drawings, Figure 1 is a sectional side elevationshowing the apparatus as applied to alift-opening. Fig. 2 is a sectionalfront elevation of the same.

In Figs. 1 and 2, A is avertical hand-shaft continued from floor tofloor throughout the height of the building.

B B are the hand-wheels, whereby the shaft A may be operated from anydoor.

C is a bevel-pinion keyed on the shaft A below each floor and gearingwith the bevelwheel C', placed at the end of atrausverse shaft D, whichis provided with lever-arms D D', to the extremities of which arearticulated connecting-rods E E, the opposite ends of which arearticulated to the under side of the sliding door F, that is supportedon rollersf, running on guides f.

G G are the cage-guides, and H is the liftrope.

A The modus operandi is as follows: The attendant if he wishes to openor close the doors from any floor will turn the hand-wheel nearest tohim, thereby rotating the vertical shaft A and communicating motion tothe transverse shaft D through the bevel-gearing C C. This will causethe leverarnns D D to move in the arc indicated by dotted linesin Fig.1, and as the lever-arms D D are connected by the connecting-rods E E tothe sliding door F the latter is caused to slide in the requireddirection beneath the floor.

It is manifest that, instead of the lever-arms and connecting-rods, asabove described, pinions on the transverse shaft gearing into racks onthe under side of the sliding door maybe substituted.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent of the United States, is-

In a device for operating sliding doors, the combination, with verticalshaft A, provided with hand-wheel B and pinion C on said shaft, oftransverse shaft D, pinion C', mounted on one end thereby and engagingsaid pinion C, arms D', attached to said shaft D, and conmeeting-rods EE, attached at one end to arms D and at the other end articulated to theunder side of the sliding door, substantially as set forth.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
